Hi there!
Using compatible numbers it would be:
12 ÷ 2 = 6.
Now when you divide it, the answer would be close to 6.
So, 12 ÷ 2 = 6 would be using compatible numbers.
Hope this helps ;)
I think it would be B ?? Because it’s the shortest one ♀️
X-3=66
x=69
69+41+(y-9)=180
110+y-9=180
101+y=180
y=79
i think it's t=0.2 Hope it helps:)
Following with the extra hint that x = 82.03 m
There are 2 ways to approach the question, but although I prefer to group up x first before plugging value, having that -0.05x^2 to group up is too annoying:
Plug x = 82.03
=> Y = -0.05*(82.03^2) + 4.5*82.03 - 6.5
= -336.446045 + 369.135 - 6.5
= 26.188955 m
Please take the time and understand the answer instead of just looking at the final result.
Also I know the number is very long, but that's the question's fault. <span>¯\_(ツ)_/¯</span>
